Appendix > Appendix F - FdkAac encoder command line

Remarks

Applies a Gargle effect to the given portion of sound under editing. This method is not available for COM interoperability: in alternative you can use the Effects.DirectXApplyGargle method.

DirectX effects requires the availability of DirectX version 8 or higher on the target system and can be applied only if a call to the GetDirectSoundVersion method returns a value higher than 7.

For further details about methods related to the use of special effects refer to the EffectsMan class.

Syntax

[Visual Basic]

Int32 nStartPosition,

Int32 nEndPosition,

Microsoft::DirectX::DirectSound::EffectsGargle fx

);
